Objective:
To evaluate the concept of bilateral same day tympanoplasty type I (BSDT) in accordance with the principle of evidence based medicine.
Methods:
A study with control was carried out in a tertiary care setting in a sample size of 60 patients suffering from chronic suppurative otitis media (CSOM). The patients were divided into two groups of 30 patients each, group-A comprised of unilateral CSOM cases and group-B comprised of bilateral CSOM cases. All the patients underwent tympanoplasty type I by post auricular inlay technique using temporalis fascia graft. BSDT was done in group-B. Graft and audiological success rates were tabulated and put to statistical examination using Student's 't' test. In addition, post-operative pain was measured by visual analogue scale and statistically analyzed.
Results:
A graft uptake of 90% and 93% was recorded in group-A and B, respectively. 27 (90%) patients reported an air-bone gap of less than 20 dB post-operatively in group-A and 94% (56 of the operated 60 ears) had an air bone gap less than 20 dB post-operatively in group-B. No case of iatrogenic sensorinueral hearing loss was recorded in this study. Further, pain was not found to be a statistically significant factor detrimental to BSDT.
Conclusion:
Bilateral same day tympanoplasty type I is a feasible treatment option in modern otology for a specific group of patients suffering from CSOM.
